Description

TECHNICAL FIELD

[0002] As one of the main grain crops in China, rice needs to go through multiple links such as cleaning, hulling, milling, grading, conveying and packaging in the processing flow, among which "conveying" and "impurity removal" are the key steps to ensure the quality and processing efficiency of rice. In the existing rice processing production line, the conveying and impurity filtering of rice are usually completed by "segmented" equipment: first, the rice is transferred from one process to another by belt conveyors, bucket elevators and other equipment, and then the impurities are separated by vibration screens, specific gravity stone removal machines and other equipment. This segmented processing method has the following significant defects: The transfer and filtering need to be completed by independent equipment, which requires additional transfer silos to connect, resulting in a large production line area, a long process cycle, and easy secondary crushing of rice during the transfer process, increasing grain loss; The existing vibration screen relies on single mechanical vibration to separate impurities, and the separation effect is poor for impurities such as rice bran, small broken rice and other impurities with a specific gravity close to that of rice, and the screen mesh is easy to block, requiring frequent manual cleaning, further reducing processing efficiency; The traditional transfer equipment needs to be manually adjusted to change the conveying path, and the discharge of impurities and dust after impurity filtering also needs manual intervention, which is difficult to adapt to the unmanned needs of modern rice processing production lines; Poor equipment coordination: different brands and models of transfer equipment and filtering equipment lack unified control logic, which can easily cause a mismatch between the conveying capacity and the filtering capacity, resulting in equipment overload or rice accumulation, affecting the stability of the production line.

Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative work fall within the scope of protection of the present application.

[0017] In order to make the above-mentioned purposes, features and advantages of the present application more obvious and easy to understand, the present application will be further described in detail below with reference to the drawings and specific embodiments.

[0018] Reference Figs. 1-2 The present application provides a rice conveying integrated machine with impurity filtering function, comprising: Gantry 1, the gantry 1 is built between the transfer conveyor belt; The planar moving assembly is installed on the gantry 1, and the mechanical grab 2 is installed on the planar moving assembly; The holding box 3 is hinged at the top with the box cover 4, and the holding box 3 is installed at the top with the screening groove 5, and the screening groove 5 is provided with a slag discharge port at the bottom; The screening box 6 is a regular polygon structure in cross section, and the screening box 6 is horizontally rotationally connected in the screening groove 5, and a space is provided between the screening box 6 and the bottom of the screening groove 5, and the screening box 6 is provided with a through port on one side, and the net door 7 is installed on the through port; The transmission mechanism is installed in the holding box 3, and the transmission mechanism is in transmission cooperation with the screening box 6; The vibration assembly is installed on the screening box 6; The high-pressure airflow assembly is installed on the box cover 4 and corresponds to the screening box 6; The control system is used for overall control of the device operation.

[0019] After the control system is started, the plane moving assembly drives the mechanical gripper 2 on the gantry 1 to move to the transfer conveyor belt, accurately grabs the quantitative rice, and then moves along the gantry 1 to above the containing box 3, opens the hinged box cover 4 through the linkage of the control system, and pours the rice into the screening box 6 in the screening groove 5. Then the transmission mechanism is started, drives the screening box 6 to rotate horizontally in the screening groove 5, and the vibration assembly makes the screening box 6 vibrate at a high frequency, so that the rice is fully turned over and not accumulated due to the regular polygonal structure of the screening box 6; at this time, the high-pressure airflow assembly sprays high-pressure airflow on the screening box 6, blows up the dust, broken rice bran and other light impurities in the rice, and the impurities fall into the interval between the screening box 6 and the bottom of the screening groove 5, and are then discharged from the slag discharge port at the bottom of the screening groove 5. After the impurities are removed, the transmission mechanism adjusts the angle of the screening box 6 so that the through opening faces downward, and the clean rice falls into the containing box 3 for storage under the vibration assistance; then the mechanical gripper 2 is driven by the plane moving assembly to return to the transfer conveyor belt for the next operation, and the control system monitors the running parameters of each component in real time during the whole process, and can dynamically adjust the rotation speed, vibration frequency and airflow strength according to the rice conveying amount to ensure continuous and stable operation.

[0020] Further optimization scheme, the plane moving assembly includes X-axis linear motor 8 and Z-axis linear motor 9, the X-axis linear motor 8 is horizontally installed on the gantry 1, the Z-axis linear motor 9 is vertically installed on the slide table of the X-axis linear motor 8, and the mounting arm is vertically installed on the slide table of the Z-axis linear motor 9. The mechanical gripper 2 is installed at the bottom of the mounting arm.

[0021] The X-axis linear motor 8 is horizontally fixed on the gantry 1, and is responsible for driving the whole execution mechanism (including the Z-axis linear motor 9, the mounting arm and the mechanical gripper 2) to move in the horizontal direction between the transfer conveyor belt and the containing box 3; the Z-axis linear motor 9 is vertically installed on the X-axis slide table, drives the mounting arm and the mechanical gripper 2 at the bottom to realize vertical displacement through the slide table lifting, and completes the action closed loop of “descending to grab rice - rising to avoid obstacles - horizontal movement - descending to pour material”. The positioner on the X-axis and Z-axis linear motor 9 can collect slide table position data in real time, feed back to the control system, adjust the motor operation parameters through accurate calculation, avoid grabbing deviation or collision with other components, and ensure that the mechanical gripper 2 can accurately dock the material taking point of the transfer conveyor belt and the material pouring point of the containing box 3.

[0023] When the transmission motor 10 is started, the output shaft drives the driving sprocket 11 to rotate, and the driven sprocket 12 is driven to rotate synchronously through the chain; the connecting plate at the center of the driving sprocket 11 is fixed to the sliding block on the annular track, so that the sliding block rotates around the annular track (coaxial with the driving sprocket 11) with the driving sprocket 11; at the same time, the screening box 6 is fixed to the sliding block through the mounting shaft, the gear on the mounting shaft is engaged with the inner tooth ring (coaxially arranged with a larger diameter than the annular track) on the side wall of the screening groove 5, and the gear rolls along the inner tooth ring when the sliding block rotates, driving the mounting shaft and the screening box 6 to rotate. Finally, the screening box 6 realizes the compound motion of "revolution + rotation", and the rice is fully turned in the box to avoid local accumulation and improve the impurity separation efficiency.

[0024] Further optimization scheme, the vibration assembly includes a vibration motor, and the vibration motor is installed on the outer wall of the screening box 6.
